Copper Sulfide Mining   Earthworks

Copper Sulfide Mining Earthworks

Complex sulfide ores containing sulfides of copper, zinc, and lead are especially common, as are complex copper, nickel, cobalt, antimony, and mercury ores. Many sulfide ores contain Pt, Au, Ag, Cd, In, Se, and Te as admixtures. Most deposits of sulfide ores are endogenous, and among those, hydrothermal deposits predominate
